摘要
基于以一维应力波为基础理论的低应变反射波法,通过桩基工程桩身完整性检测分析,对不同类型的缺陷桩实测信号进行定性分析,研究实测波形曲线反射信号特证与桩身完整性之间的关系,结合地质和施工情况综合分析,确定桩身缺陷程度及其类型,从而进一步准确的判定桩身完整性类别,为提高基桩质量检测的精确性和可靠性提供参考。
Low strain reflection on the one-dimensional stress wave theory wave method based on the pile foundation engineering pile integrity test analysis,qualitative analysis of the measured signal of defective piles of different types,to study the relationship between the measured waveforms of the reflected signal characteristics and pile integrity,comprehensive analysis of geological and construction conditions,to determine the degree of pile defects and its types,thus further accurate determination of pile integrity categories,to provide reference for improving the accuracy and reliability of the pile quality test.
